SURFACE-COATING MACHINE.

Specification of Letters Patent.

Patented Aug. 16, 1921.

Application filed September 30, 1920. Serial No. 413,830.

To all whom it may concern:

Be it known that I, STEPHEN W. Booms, of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Surface- Coating Machines, of which the following is aspecification.

This invention relates to a machine for automatically applying a fluid to the surface of work such as shoes or other articles, and has for its object the provision of means for supporting the work and the fluid-applying device and rotating one relative to the other whereby the fluid such as varnish, shellac, cement or the like, may be applied to redetermined portions of the surface of t e work.

The nature and advantages of the invention will be better understood when the following detail description is taken in connection with the accompanying drawings, the invention residing in the combination and arrangement of parts as claimed.

In the drawings forming part of this specification, like dicate similar parts in the several views and wherein Figure 1 is a side elevation showing my improved machine on which is shown as being mounted a shoe-upper to which is being applied a layer or narrow line of cement.

Fig. 2 is a plan view of the machine illustratin a shoe-upper and a brush by means of which a narrow line of cement is being applied thereto.

Fig. 3 is an enlarged end view showing the carriage with the shoe form rotatably mounted thereon and in contact with the guide roll.

Fig. 4 is a section on line 4-4 of Fig.3.

Fig. 5 is a section on line 5--5 of Fig. 3, showing the pins which support the work.

Fig. 6 is a modification illustrating two sets of work-supports connected together to work in unison with each other.

It is found in practice in the construction of shoes, such as tennis shoes and the like, where the foxing portion is secured to the upper by cement, to be of advantage to be able to apply the cement about the lower numerals of reference inedge of the upper, automatically, thereby increasing the roduction, laying the cement more uniform y, and doing away with skilled labor for this service; and the following is a detail descriptionof one means I by which this result may be accomplished.

With reference to the drawings, 10 designates the base of themachine on which is mounted two frame-standards 11 and 12. On the standard 12 I have mounted a plate 13 having 1ts front face provided with two parallel, longitudinally-disposed grooves 14 and in each of which grooves are mounted two rolls 15 to carry the carriage 16, which carriage 1s supported in position against the face of the plate 13 by means of the bolts 17 passing through the back plate 18. POSItIOIIGd against the front face of the carriage-plate I have mounted a form-plate 19 which late is mounted on and keyed to th rotata le short shaft 20. This shaft is also mounted to rotate in the carriage-plate 16 and in order to permlt of longitudinal movement of the carriage this shaft is provided with a roll 21 which rotates with the shaft in the slot 22 formed in the plate 13 while a slot 23 of the diameter of this shaft is formed in. the frame member 12.

A rotating motion is transmitted to this short shaft from the pulley 24 through the p1n1on 25, gear 26 and telescoping connecing shaft 27, the length of which shaft changes to accommodate the travel of the carriage.

In order to control the longitudinal movement of the carriage 16 on its ways I have provided a guide roll 28 against which the edge of the form 19 rests being held in contact therewith by means of a counterweight 29 through the cord 30 which leads over the pulley 31, but a spring or other suitable means ,may be employed for this purpose.

The form 19 is always of a shape .to control the movement of the work relative to the fluid-applying device, The work in this particular case is shown to be a shoe-upper to which I desire to apply a narrow line or strip of liquid cement for the urpose of fastening the foxing portion of t e shoe sole thereto and in obtaining this particular result I mount a air of pins 32 on the form 19, which pins are presently described.

mg upon a shoe assaeee ada ted to enter correspondilig holes 33 in thelhster shoe-support 34 see ig. 5, and on this last I have mounted a shoe-upper '36 to which the cement is to be applied.

I do not wish to be restricted to the use of any particular device for applying this cement to a shoe-upper as any suitable means may be employed but for convenience have herein shown a brush 37 which is mounted on a support 38 extending outward from the guide roll 28, the bristles of the brush being on substantially as the contact surface of the guide Troll whereby by the rotation of the form 19 the surface to be treated is continuously presented to the brush.

he cement may be automatically supplied to the brush from the tank 39 above or other suitable source through the pipe 40, and by means of this brush a line or narrow strip of cement may be applied about the lower edge of the upper and after one or more coats have thus been so applied the shoe-upper may be removed and the foxing portion applied to this cemented surface, thus savin much time and the employment of skilled abor in performing this work.

Neither do I wish to be restricted to the use of a brush for applying this cement to the work as in some cases a pipe 41 may be employed which is led over the portion to be treated and the fluid may be sprayed or otherwise spread upon its surface.

I have shown and described my improved machine as manipulating a shoe-upper for the purpose of applying cement thereto, but

do not wish to be restricted to the apphcation of cement to a shoe as any other fluid such as varnish or shellac may be applied to any portion of the surface thereof; neither do I wish to be restricted to operatupper in this machine, as the same may be adapted for manipulating and treating the surface of any other kin of work. Thenagain I have shown the work as being rotated and the fluid-applying device as held in a relatively fixed position, but in some instances the wor' may be fixed and the fluid applying device revolved about the work. I

I have also shown and described a machine for operating upon a single piece of work, but in some cases a plurality of forms and work supports may be employed and driven in unison, one arrangement of which construction is illustrated in Fig. 6, both of the forms shown being operated in unison through a sprocket chain 42 working over the sprockets 43.

This fluid-applying machine is very simple in construction and by its use skilled labor may be dispensed with and much time saved in the application of fluids to the surfacessof work to be treated.

. he foregoing description is directed the same plane :olely toward the construction illustrated,

ut serve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by claims.

2. In a machine of the character de-' scribed, means for supporting the work, a non-rotatable fluid spreader, means for supporting said spreader, means for rotating one relative to the other, and means for supplying fluid to said device to be automatically spread upon the surface of the work.
